Deoxys

[Shadowth117]

Thats what I was thinking. He could use Psycho Boost and pull a Giga Bowser. He could turn into Attack form and all him attacks a way stronger and have much more range.

As far as how Deoxys plays, I kinda think it would be cool to have him as a composite character of sorts. Not a direct clone of any one character mind you.
Example:

^B Zen Headbutt (Normal Form)- Works a bit like a combonation of Fox's and Pikachu's up B. He will charge in a direction for a good distance, and if you hit another direction, he will pause halfway through it and go in that direction like Pikachu.

<>B Super Power (Attack Form)- This is a charge attack. The charge can be broken up into 4 parts. each part adds one of the 4 tentacles to what will in the end be a stab like punch. The less tentacles in the punch, the faster the charge and punch, so you have to consider speed versus power.

vB Mirror Coat (Defense Form)- Curls and creates a shield like bubble that, upon appearing will shrink very fast, after which he will swing his arms out. The bubble will reflect thrown objects, the exit will send items on the ground flying, as well as hurting anyone close enough.

B Night Shade (psychic?) (Attack Form)- Does that attack from the movie. To add a twist to it from being another boring energy charge attack, you could also aim it a bit like Snake's guided missile, but with less over all control So kinda like Pit's arrows I guess).

I figured his running A attack could be a Slash like attack with Speed Form.

Not to ruin your idea, but wasn't psycho boost an attack and not a stat buff? I mean you could use it that way, but Giga Bowser and Warioman already use that idea.

I really like your ideas for his other attacks though. I don't see problems with them.
